Mathlectics

My daughter gets a little bit frustrated with Maths and Mathlectics. She knows her times table, but is a bit slow with some numbers and this adds to her frustration when doing Maths homework. So I've found it helps to get her to write out the times tables she is a bit slower with before starting each session (6, 7, 8 and 12). This helps her enormously especially when she's tired, but is it "cheating" or counter-productive? I'm not talking basic mental arithmetic like 6 x 5 = but questions where the hard part is figuring out what the sum is e.g rounding up

765 x 530

So the hard part would be figuring out that it's 8 x 6. The answer is less important. If that makes sense? She'll do the hard part OK, but then get bogged down with the basic multiplication.
